AMENDED AND RESTATED
CHANGE OF CONTROL CASH SEVERANCE AGREEMENT

        THIS Amended and Restated Change of Control Cash Severance Agreement (the "Agreement") is dated as of August 1, 2007, by and between BG Medicine, Inc., a Delaware corporation (the "Company"), and Robert N. McBurney (the "Employee").

        WHEREAS, the Company and the Employee entered into that certain Change in Control Cash Severance Agreement dated as of November 28, 2006 (the "Original Agreement") and the parties have agreed to amend certain provisions of the Original Agreement as contained herein;

        WHEREAS, the Board of Directors of the Company (the "Board") has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication of the Employee, notwithstanding the possibility, threat, or occurrence of a Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of the Employee by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control and to encourage the Employee's full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Employee with compensation and benefits arrangements upon a Change of Control which ensure that the compensation and benefits expectations of the Employee will be satisfied and which are competitive with those of other corporations. Therefore, in order to accomplish these objectives, the Board has caused the Company to enter into this Agreement;

        NOW, THEREFORE, in consideration of the covenants and agreements set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby mutually acknowledged, the parties hereto covenant and agree as follows:

      all of the assets or capital stock of the Company (other than in a spin-off or similar transaction) or any other acquisition of the business of the Company, as determined by the Board. For purposes of this Agreement, "Change of Control" shall be interpreted in a manner, and limited to the extent necessary, so that it will not cause adverse tax consequences for either party with respect to Section 409A of the Internal Revenue Code of 1986, as amended ("Code Section 409A"), and any successor statute, regulation and guidance thereto.

    (e)

    (i)
    the assignment by the successor to the Employee of any duties inconsistent with the Employee's position with the successor (including status, offices, titles and reporting requirements), authority, duties or responsibilities, or any other action by the successor which results in a diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the successor promptly after receipt of notice thereof given by the Employee;

    (ii)
    the successor's requiring the Employee to be based at any office or location other than one within thirty (30) miles of the Company, as set forth in Section 3(b) hereof; or

    (iii)

    (iv)
    For purposes of this Agreement, "Good Reason" shall be interpreted in a manner, and limited to the extent necessary, so that it will not cause adverse tax consequences for either party with respect to Code Section 409A, as amended, and any successor statutes, regulation and guidance thereto.
